Yes, that should not talk about 64-bit systems but about the length of the word the memory controller uses to create the ECC check bits out of. That whole doc needs checking/fixing. > The extra 8 bits which are used for error detection and correction > are referred to as the *syndrome*\ [#f1]_\ [#f2]_. Well, I know it as "The syndrome field uniquely identifies the failing bit positions of a correctable ECC error." and depending on the error severity you can have correctable and uncorrectable syndromes. I don't think the syndrome is the ECC word but it might be, depending on the ECC algorithm used or it might be that what I pasted above. That would need deeper digging.
